IMPROVEMENT IN POCKET-INHALERS.

Specification forming part of Letters Patent No. 146,589, dated January 20, 1874; application filed December 12, 1873.

provements in Pocket-Inhalers, of which the following is a specication:

The invention relates to that class of inhalers which are portable, and are iilled with various pun gent or medicated ingredients for thev use of persons troubled With asthma, catarrh, Src.; and the invention consists in combining, with a hollow spherical elastic ball, a single central combined air-pipe and inhaling-tube, through which the air is drawn in and the medicated vapor expelled by merely pressing the ball, as hereinafter fully explained.

In the drawings, Figure l is a sectional elevation; Figs. 2 and 3, variations in construe tion.

A represents an elastic ball or sphere, made preferably of rubber, and hollow, with a hole at top and bottom for the admission of the combined air-pipe, standard, and inhalingtube B. This is constructed of a single piece of wood, with shoulders a ct, into which the Y elastic sphere A springs, and holds of itself at top and bottom, as shown. This inhaling-tube has a central air-passage, b, which `runs from the nozzle c down as far as necessary, and has two or more air and vapor holes, d d, formed at right angles with the central air-passage b inside the ball, and leading thereto, by which, after the air has filled the ball and become medicated by contact with and passing through the compound, it is expelled by a slight pressure on the ball through these holes d d out of the central passage b into the nostrils or mouth of the operator or patient. A cover, f, will be` attached by a string to put on the tube to keep the strength unimpaired.

The compound will be put in the hollow ball around the central tube B, but the tube itself may be made hollow and filled with the compoimd, having holes in it to admit the air forced Vin by the action of the ball, as in Fig. 2; or a ball may be lled and a nozzle set in, as in Fig. 3. The ball acts as a pump, sucking in the air as rapidly as it is expelled by merely relaxing the pressure of the hand. It sets tightly in the grooves made by the shoul ders a. af, and is thus perfectly air-tight.

`I am aware that hollow elastic balls have been used in connection with perfume, and for syringes, but never, so far as I am acquainted,

as a receptacle for a medicated compound, and p `cated compound, all arranged to operate as and for the purpose hereinbefore specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
